What this trial studies

This observational registry aims to assess the risks of adverse pregnancy outcomes, such as preterm birth and hypertensive disorders, following exposure to the RSV vaccine during late pregnancy (between 32 and 36 weeks of gestation). The study will collect data on various maternal and neonatal outcomes to evaluate the safety of the vaccine in this specific population. Participants will include pregnant individuals who have received the RSV vaccine within the specified gestational period, and the registry will track their health outcomes and any complications that may arise. The findings will help inform the safety profile of the RSV vaccine for pregnant individuals and their infants.

Why it matters

Potential benefit: If successful, this study could provide critical safety information regarding the use of the RSV vaccine in pregnant individuals, potentially leading to improved maternal and infant health outcomes.

How similar studies have gone: While this study focuses on a specific vaccine and population, similar observational studies have successfully assessed vaccine safety in pregnant individuals, providing a foundation for this research.
